## Japan's Military Steps Out: 11 Foreign Weapons Protection Missions in 2025 for U.S., U.K.
Japan's Self-Defense Forces have executed at least 11 missions in 2025 to protect the military assets of allied nations, a tangible and repeated application of its expanded security laws. These activities, conducted for the U.S. and British militaries, represent a significant operational shift from Japan's historically defensive posture. Each mission directly implements the 2016 security legislation that allows Japan to come to the aid of allies under attack, moving beyond theoretical policy into active, real-world military cooperation.

The missions fall under the category of 'protection of weapons,' a key provision that permits Japanese forces to defend allied ships, aircraft, and equipment during peacetime or in 'grey zone' situations short of full-scale war. This is not a one-off exercise but a sustained pattern of activity within a single year, indicating a new normal in Japan's defense operations. The repeated engagements with the U.S. military were expected, but the inclusion of the United Kingdom highlights the broadening scope of Japan's security partnerships under these laws.

This operational tempo signals Japan's deepening integration into allied military frameworks and a steady erosion of post-war constraints. The consistent use of this authority places the Self-Defense Forces in more frequent and complex coordination roles with foreign militaries, increasing their operational experience and interoperability. It also reinforces the strategic alignment between Tokyo, Washington, and London, while testing the implementation and limits of Japan's controversial security legislation in practice.
